Meridiam, announces its investment in CEOG (Centrale Electrique de l’Ouest Guyanais), currently the greatest project worldwide of a power generating plant storing intermittent renewable energy using hydrogen.

The power plant will provide stable electricity day and night to over 10,000 households in French Guiana through its massive hydrogen-based renewable energy storage system.

Meridiam is acquiring 60% of CEOG alongside HDF Energy to finance and develop this project. This operation is accelerating the development of the project, which is scheduled to be commissioned in 2020 to produce stable, non-polluting electricity for the benefit of the inhabitants of western French Guiana.

HDF Energy is the world's leading producer of stable electricity from intermittent energy sources, combining a 55 MW photovoltaic park with the world's largest 140 MWh hydrogen-based renewable energy storage capacity, coupled with battery backup storage. This combination allows stable electricity to be produced over the long term with 100% clean energy.

This investment is a further illustration of Meridiam's voluntary approach to meeting the challenge of the energy transition, in the same way as electric mobility, biogas and biomass, or energy efficiency and demand management, sectors in which Meridiam has also invested.
